Lots of people have cars that came with a built-in remote control that could be used to open their garage door. Most people end up not using them, because they don’t seem to work. It might be possible to reset the transmitter.
Audi, Dodge and a number of other manufacturers include built-in transmitters that work with rolling code garage door openers. Most electric openers manufactured after 1997 are equipped with the rolling code technology.
The technology was created to prevent your transmitter from opening your neighbor’s door or to prevent a thief from opening your door with any transmitter. The older technology was a dip-switch system. The system was still used until 2004 by some manufacturers.
So, if your garaged door opener was manufactured after 2005, it should include the rolling code technology. An older car might not be compatible with a newer door opener. A newer car might be compatible with an older opener.
In order for the transmitter to work, it must transmit a signal on the same frequency as the receiver of the garage door opener. That shouldn’t be a problem.
The receivers of all electronic openers are set to receive a signal in the 300-400 MHz frequency. Those openers with rolling code technology are set to operate at either the 315 MHz or 390 MHz frequency.
You can use the color of the programming or “learn” button to figure out what frequency your receiver is set for if you are unsure. If the programming button is green, orange or amber, the frequency is 390MHz. If it is purple, the frequency is 315MHz.
The owner’s manual of your vehicle should tell you what frequency the transmitter is set for. If not, you should be able to find out from a dealer or through the internet. Some of the transmitters are “universal”. They are supposed to work with any opener, regardless of the system.
If you have an in-car transmitter that doesn’t seem to work, it probably just needs to be reset. The factory would have programmed the transmitter. You need to clear that programming out.
In most cases, there are two buttons located on the outside of the in-car transmitter. You should hold those buttons down simultaneously, until a red light starts flashing rapidly. Be patient. It can take as long as 60 seconds, before the red lights start to flash.
If you do not see a light after 60 seconds, check to see if the transmitter requires some kind of fuse or battery. You might also turn on your car engine. Some of the transmitters will not operate if the engine is not running.
The next step is to go to your opener’s programming button and press it. The indicator light will turn on and remain lit or blink.
The final step is to return to your car and push the transmitter button until the garage door starts moving. You may have to press the button three or four times, but once it starts moving, your transmitter is set. It’s as simple as that.
